TOOL HANDLE.

Application filed April 18, 1927.

This invent-ion relates generally to tools, and has more particularreference to a novel tool handle structure.

The invention has for an object the provision of tool handle structurewhich will securely and efliciently hold a tool without the use ofrivets or screws cooperating directly with the tool. A saw may beconsidered for the purposes 01' disclosing the invention, though theinvention is not limited to the saw, it being applicable to other toolsalso. Commonly a handle is attached to the blade of a saw by means ofscrews, or rivets passing through the blade and handle. Necessarily thecontacting surface between the blade and adjacent portions of the screwsis small, and therefore a large strain exists between these parts,resulting in rapid wear and a loosening oi the parts. It is an object ofthis invention to overcome these defects.

The invention has for a furtherobject, the provision of a tool handlestructure which may be applied to tools at a reasonable cost.

For further comprehension of the inven, tion and of the objects andadvantages thereof, reference will be had to the following descriptionand accompanying drawing and to the appended claims in which the variousnovel features of the invention are morepzn-ticularly set forth.

Referrin to the accompanying drawing, forming a material part of thisdisclosure:

Fig. 1 is a side view of a saw embodying the principles of thisinvention.

Fig. 2 is a fragmentary bottom view thereof.

Fig. 3 is a vertical sectional view, taken 011 the line 33 of Fig. 1.

F t is a horizontal sectional view corresponding to the section taken onthe line 44.- of Fig. l but disclosing a modification of the invention.

Fig. 5 is a horizontalsectional view similar to Fig. 4-, but disclosinganother modification of the invention.

Fig. 6 is a fragmentary side view of the saw blade of Fig. 1.

The reference numeral indicates generally a saw blade provided at oneedge with a projecting portion 11, and on the same edge but below theprojecting portion 11, with a niche 12. A handle 13 is provided with asubstantially arranged L-slot 14, with the long arm of the L-slot cut infrom one end of the handle. The saw blade 10 is slid into the long armof the L-slot, and the projection Serial No. 184,456.

11 into the short arm. A stop screw 15 is cngaged in the handle 13 andabuts against the top of the projecting portion 11, determining theamount to which the blade enters the handle. A pin 16 is engaged in thehandle 13 and has a retaining plate 17 pivotally mount ed thereto, theretr ning plate being swingable toengage in F19 niche l2 and hold theblade against displacement from the handle.

In the modification illusrated in Fig. 4 the saw blade 10 is providedwith a circularly shaped n'ojecting portion 11 having an aper ture 12therein and is slid-ably arranged in the handle 13. The handle 18 isformed with a cavity 18 closed by top inen'iber 19 having a aperture 20through which rod L1 is slidably disposed. The top of rod 21 is providedwith a knurled head and the rod has near its bottom end a flange Aspring 24 is encased in the cavit 1S and acts between the top member 19and the flange 23, normally urging one end of the rod into the aperture12 holding the blade 10 against displacement. L

The modification illustrated in Fig. 5 discloses the blaue 10 providedwith a corrugated end 11 and slidably arranged in handle 13. The meansillustrated in Fig. 1 may hold this blade against displacement.

\Vhile I have illustrated and described the preferred form, constructionand arrangement of the several lcmcnts emplobd'. it will be under. codlat the device is nevertheless, susceptible cl considerable modificationtherein, and I therefore 1' serve the right and privilege of resortingto all such changes as may be fairly embo lied within the spirit andscope of the invention as claimed. 7

Having thus described my invention, what claim as new and desire tosecure by United States Letters Patent is:

The combination with a saw handle, having a blade slidablc therein, oi ascrew ongaged in the handle and forming an abutment for the blade toprevent sliding in one ClliSCJlOll, the blade being termed with a niche,a pin engaged in the handle. and a retaining plate swing-ably connectedwith the pin, the said screw being so positioned that when the bladeabuts the screw the niche is aligned 1 01 engagenient with the retainingplate, as a means for holding the blade in place.

In testimony whereof I have afiixcd my sig nature.

MICHAEL MENDEL.
